Humans evolution

Humans must be the dominating species on the planet earth.
Don't you agree?
I mean.. There's humans everywhere on the planet, exept for a very few places, and there's over 6 billion of us.

It's very few other animals who has the same number of individuals as humans have.

It's only some insects and some other small animals, as we know, who is having the same amount individuals as we have.

In contrast to most, maybe all, of the other species on the planet, we can live in almost all of the continents. The only continent were we doesn't live is the antartic.

We use lots of space on the earth, to our houses and cities and we claer forests to get resources and so on.

We destroy a lot of the natural habitats the plantet original is based on, and what we lived in once a time.

Soon, will there maybe only be a very few species besides humans on the ground of the earth?

Sometimes we tend to forget where we came from, and how the environment was before we evolved to what we are today.

Darwins evoulutionary theory tells us that the strongest (the one that best can adjust and so on) survive, but whar about now?

Is it the meaning that we should be the only sppecie in the ground?

Evolutionary theory and difference

When you talk about the evolutionary theory, you say the strongest survive.
But then why are we all so different?
The strongest survive.
Dosn't it meen we all should be identical, or almost identical?
You can say we are, but if that's true, why does we have so different interests and have so different strengths and weaknesses?
Yeah, maybe if the difference only was a little bit of variation, but still connected and within the same subject?

I think the simple answer is that we need all sorts of talents to build up a community like ours, and without the difference between people, there wouldn't be any chance that we would develop ourself, and the community would stop developing too.
We need suport from each other, else we can't continue the development, and that would result in the suspension of the evolution.
That's why we need to be different.
And it's also a good way to put variation in our daily life, and make the day different from the last.

The evolutionary theory says the strongest will survive, but it's not only one, who is the strongest; it's a lot!
